Clarifier short circuiting
WebHowever, circular clarifiers are almost universally affected by the short-circuiting that is caused by density currents that are developed within the tank. Density current baffles mounted inside the clarifier have been found to be the most effective means of minimizing the effects of short-circuiting and improving effluent quality. WebIn a square or circular basin (clarifier), water typically enters the basin from the center rather than from one end and flows out to outlets located around the edges of the basin. ... Short-circuiting. Another major cause of inefficiency in the sedimentation basin is short-circuiting, which occurs when water bypasses the normal flow path ...
